I don't think you can go to 2.71 from 3.71.

I think the only way to get to 1.5 from 3.71 is pandora battery / magic memory stick which like you said needs 2 psp's .

I'm pretty sure there's no other way to do it.

You could always try and buy a magic memory stick / pandora's battery?

They're not that expensive.
